I can drive the truck for a day (10-200 miles) and have no issues at start up or it will crank over slow, start and run fine but in tow/haul or not in tow/haul. Tow Haul mode will not work, it will only only activate at start uip on it's own at times and It will not turn off.
Any suggestions? All I have heard from people is the computer, Chevy dealers say it is not and want 90-100 dollars an hour to diagnose, and we all know how much that will eventually cost.
FYI I am a marine diesel technician for the past 15 years, 9-1100 hp range, mechanicle and common rail fuel systems, not an auto mechanic so I am at al little bit of a disadvantage when it comes to vehicles.
Best regards, Roger
No, I do not have On Star. I also do not have a beacon switch as a dealer suggested.
This will happen with all equipment turned off, radio, fan, etc. I have not used the factory security and it still happens.
I have no after market add ons/ up grades installed. The truck is the same as the day I purchased it new in 2001, stock. Thanks, any other questions, please ask. Roger
have the same problem?
